when i slow down to a stop light and if it quits due to on going carb trouble.
It turns over like the battery is dead and wont start and then if I let it set for about 5 minutes it will turn over at normal speed and fire up.
I have replaced battery and starter and it still does it.
I dont know what to check from here.
It wont idel after it gets hot either.

timing might be the culprit, but dont disregard that carb issue you have, chances are in your case, your dumping fuel into the cylinders when stopping, and being the cylinders are loaded with fuel, and incorrect timing, the starter cant turn the motor over effectively, check both , idle it for about 2-3 minutes, and while still idling, does the exhaust wreak of fuel?
